Chicago White Sox minor league SP Scott Olsen, currently pitching for Rookie-level Bristol, allowed one run on one hit over one inning Friday, June 29, in his season debut. He walked none and struck out one. Olsen missed the entire 2011 season with an injured left shoulder.

The Pittsburgh Pirates released SP Scott Olsen Saturday, May 14. He entered spring training as a candidate for the fifth starter job, but fell out of the race due to a hamstring strain. He eventuall ended up on the 60-day disabled list due to the fact he couldn't build up enough arm strength in his inflamed shoulder.

Pittsburgh Pirates SP Scott Olsen (hamstring, shoulder) continues to slowly build arm strength, but remains a while away from contributing, reports Jenifer Langosch, of MLB.com. Olsen continues to work out at the team's spring facility in Florida. He has been throwing bullpen sessions, while working in one extended spring game. He'll work in a second game later this week.

Updating previous reports, Pittsburgh Pirates SP Scott Olsen (shoulder) was placed on the disabled list due to shoulder inflammation and not due to his hamstring injury he suffered in camp, the Pittsburgh Post-Gazette's Colin Dunlap reports.
